SpletWell simply explained, an algorithm that is used for finding the shortest distance, or path, from starting node to target node in a weighted graph is known as Dijkstra’s Algorithm. This algorithm makes a tree of the shortest path from the starting node, the source, to all other nodes (points) in the graph.
